Sun blocker

[Napo dwarf]

Hello,

tell me I'm worried about overheating in our house

and I wondered if there was not a little software to calculate the sun breezes
angles of the blades and range of the said sunbreak depending on the orientation of the facade

what I envision is to allow it to be sunscreen summer and shutter in winter by rocking it. They will be installed under the existing cap

if it does not exist I guess I have to take the SOHCAHTOA ^^

Thank you in advance for your replies

Uh it's not the principle of what is called a store?

[Napo dwarf]

yes for the moment that's what there is but I would like something outside to avoid the sun rays from 11h the morning of June to August
and then that it serves as a shutter in winter just by rocking (reduction of losses at night)

the stated purpose and to remove the blinds from the inside, I do not like ^^

[Christophe]

Ah well it's called an external awning ...

It's rare but it exists, there are even some who are motorized ... I think ...

Now it's like a "Venetian blind". Ok for the sun.
But when there is wind?
Ditto if it is at the rdz, someone can always lift the slat to squint inside.
As for serving as a component too? There is then an easy break-in. Insurance?

we already have no flap and we are assured like that ^^

I think in winter especially the radiation losses at night

tomorrow I'll post you a photo that will be more telling

basically we got that

but under the cap we must have max 15 cm I do not fit the blinds
unless the slats are very very thin and it does not take up too much space once back

I will send you a diagram of what I was thinking about but here I am slammed ^^

I thank you for your interventions it makes me happy

that's not to say, but in the high Alps, we use the outer shutters, and that's pretty good, and for the summer sun that hits the windows, and for the cold cold of the winter. wood and hinges and clasps, a minimum of ecological load, economic, for maximum efficiency.

unless you like to live in the shadows, blind shutters like indoor blinds, it does not ...
To avoid too much sun but keeping a good brightness and view on the outside:
either a roof projection, an external awning (to be linked with an automatic retracting system if the wind rises when one is absent) or even sun screens to be placed on the windows ... There are also photosensitive windows ( like glasses of the same kind), but it's still expensive ...
At home, in apartment, there is the wide balcony of the neighbor of the top which prevents the sun to return in summer: in my apartment it stays cool in summer, provided not to open obviously (ventilation by VMC), the neighbor of above dies of heat even by closing all its shutters PVC white

This is the most "economical" plan I have ever seen!

[Napo dwarf]

this is for Christophe, a luxury plan done on Paint ^^








I measured the slope of the cap it is 15 °

I think now it's more talking
